china rotary table abrator quotation
Rotary table in market mainly includes 4 kinds of mechanism that is worm gear, roller cam, DD driver and harmonic structure. The following is the introduction:
1. worm gear: it’s one of the most popular structrue in NC rotary table because of its irreversibility and costs.The worm is generally made of bronze, but the wear resistance is poor. In order to improve the service life, some manufacturers use the alloy steel.
3.DD motor: it’s the most efficient rotary table with the highest precision. It has the highest precision because it has no mechanical structure, which is directly driven by motor , no reducer. It has high technical difficulty and high price. It is generally used for five axis machine tools.
IP rated rotary tables provide more possibilities for humidity and dusty environment in actual working conditions, like CNC drilling work, CNC grinding work, laser marking and laser cutting work, etc.
High precision and excellent IP rated performance makes the high precision and accuracy work possible, such as diamond cutting rotary task, phone production and inspection rotary task, etc.

The rotary table is an accessory for the CNC floor type boring and milling machine. It can be working together with the floor type boring milling machine for milling angle, reverse boring, polyhedral machining, and other complex machining processes. It could do five sides machining if the main machine equipped the angle milling head.
CNC rotary table is a common part of CNC milling machine, often used as a servo axis of CNC milling machine, namely C axis of vertical CNC milling machine and B axis of horizontal CNC milling machine. The CNC rotary table includes the foot of the turntable, a round turntable surface, four rolling bearing parts arranged on the upper surface of the foot of the turntable, and a center with a self-aligning bearing installed at the center of the upper surface of the foot of the turntable. Support, each rolling bearing component includes a rolling bearing and a support that supports the rolling bearing through the axle. The center of the lower surface of the turntable is provided with a vertical downward axle. The turntable is installed on the foot of the turntable. The inner ring of the self-aligning bearing is fixed, and the rotating surface of the rolling bearing is in rolling contact with the lower surface of the turntable surface.
The CNC rotary table has an inclinometer with two orthogonal test axes as the test tool. The inclinometer is set at the center of the turntable surface to be leveled, so that the two orthogonal test axes of the inclinometer are parallel to the turntable surface, by adjusting the milling machine turntable. The leveling mechanism under the base makes the tilt angle value output by the two test shafts of the inclinometer turntable in the leveling state.
CNC rotary table and swing head are the key components of multi-coordinate CNC machine tools. Traditional rotary tables and swing heads using high-precision worm gears and other transmissions are not only difficult to manufacture, costly, but also difficult to achieve the speed and accuracy required for high-speed machining. Therefore, it is necessary to develop a new electromagnetic drive system for the CNC milling machine turntable and swing head in a different way to realize the zero-drive drive of the rotational motion coordinates of the CNC machine tool.
1. The CNC turntable uses modular design technology. The PAN turntable and TILT turntable are independent components, which are easy to disassemble and can be controlled by linkage or individually.

Mr. Straessle is pL Lehmann product manager at Exsys Tool. He says that while five-axis machines have become more affordable, they still can be two to three times the cost of a three-axis VMC, depending on the model. Therein lies one advantage to rotary tables, which, when installed on the bed of a three-axis VMC, combine a rotational C axis and a tilting A axis to enable the machine to perform either five-axis positioning work (aka 3+2 machining) or full five-axis contouring. Three-axis VMCs outfitted with two-axis rotary tables are commonly smaller than five-axis machines, too, saving valuable floor space. Unfortunately, they also tend to have tighter work envelopes, meaning a sizeable rotary table will be more restrictive of a machine’s movements.
A compact rotary table preserves work envelope space, providing more room for spindle and tool movement. Plus, shops have the option to use just the rotary table, mount standard vises next to it or remove the rotary table altogether, which is made simpler when the rotary table has a zero-point-type locating system to eliminate the need for alignment when it is removed and then remounted.
That said, Mr. Straessle says compact rotary tables still must possess design elements that enable them to perform effectively for a range of work. Here, he details four such features inherent to the pL Lehmann 500 series of modular-designed rotary tables, available in North America through Exsys Tool.
1. Load capacity. The compact 500 series provides load capacities that, in the past, were only available with larger rotary tables. For instance, the 3-inch rotary tables in this series are generally half the size of comparable units, but can handle workpiece loads as heavy as 400 pounds, he says.
2. Speed and torque.Rotary tables commonly use either direct-drive or gear-driven technologies, the former able to achieve high rotational speeds and the latter offering high torque. The 500 series uses the company’s pre-loaded gear drive (PGD) design, which is said to offer the best of both worlds in terms of high speed and high torque while being as much as four times as rigid as direct-drive systems. Plus, it enables the rotary tables to generate rotational speeds as fast as 160 rpm with virtually zero backlash.
3. Spindle clamping power.Once a rotary table is oriented to the desired position, an effective spindle clamping system is needed to securely hold that position during machining operations. Some rotary tables use an external intensifier or some other type of standalone hydraulic unit combined with disc braking to achieve necessary clamping forces. Conversely, the 500 series features an integral unit that converts air pressure into hydraulic holding power, using a
4. Monitoring system.The 500 series features a self-contained, internal monitoring system used to track and record vital rotary table information, including temperature, rotational speed and clamping force. It also detects internal pressure decay.
In addition, the rotary tables have USB ports to enable users to download monitoring data to log the operational history of the table. Not only does this data highlight crashes or malfunctions, but it also facilitates more effective preventive maintenance by offering early warnings to possible issues so users can avoid unplanned downtime. Plus, the monitoring system activates a series of LED warning lights when it recognizes a potential problem. For example, a blinking orange light is an alert to a situation that can be addressed before it becomes serious, while a continuous red light means immediate attention is needed. Because these rotary tables integrate with all the common machine tool CNCs, users can have warnings displayed on the control screens, too. By connecting a laptop running software such as pL Lehmann’s TeamViewer, users can also solicit assistance via the Internet from a company technician who can log on to assist in troubleshooting.
Mr. Straessle says the company guarantees the spindles on its standard rotary tables to achieve runout of 5 microns and its high-accuracy models to achieve runout of less than 3 microns (the latter is commonly used in grinding applications). In addition, glass scales provide ±1-arcsecond positioning capability for the C axis. These rotary tables are also sealed to prevent internal contamination that could hinder performance and feature a motor housing internally pressurized with oil to achieve an IP67 rating.
